This is template .cls file

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% AUTHOR
% if corref is not set, we will use first author with an email as a corresponding author
% \corr@author@id -> {au1}
% \corref@list    -> {aff1,aff2}

\newif\ifauthorcorref@notset \authorcorref@notsetfalse


\def\bmc@author{\@ifnextchar[{\author@fmt}{\author@fmt[]}}

\def\author@fmt[#1]#2{%
  \stepcounter{author}{%
  \csname author@cmd\endcsname%
  \author@correffalse%
  \xdef\author@id{au\the\c@author}%
  \setkeys{author}{#1}%
     \@ifundefined{num@author}{\@tempcnta=10\relax}{\@tempcnta=\num@author\relax}%
     \def\a@sep{, }%
     \ifnum\@tempcnta>1\relax%
       \ifnum\c@author=\@tempcnta%

Best Answer

The link you provided shows an example in which the second author is the corresponding author. Just make sure your corref is inside the correct \author[].

\author[
 addressref={aff1}, 
 email={jane.e.doe@cambridge.co.uk} 
 ]{\inits{JE}\fnm{Jane E} \snm{Doe}}

\author[
 addressref={aff1,aff2}, 
 corref={aff1}, % This is the command that designates corresponding author  
 email={john.RS.Smith@cambridge.co.uk}  
 ]{\inits{JRS}\fnm{John RS} \snm{Smith}}
